We speak of the challenge of midlife, but could there be another dramatic shift that occurs in the twilight of life? We say that someone is growing old, referring alike to those who are being dragged into the last stage of existence and those who are still actually learning and developing wisdom.
As we enter the evening of life, our sight and hearing begin to fail, our bodies weaken, our power to move about may be restricted or taken from us. The body becomes rebellious, impatient, fatigued, and possessive. There are more frequent visits to medical facilities and health professionals. Bodily functions become a focus of new daily routines.
